Comcast Buys Social-Networking Site Plaxo

Comcast (CMCSA Quote) will acquire social networking site Plaxo in a move aimed at unifying social media across the Internet and television.

According to a blog post on the company's Web site, Plaxo CEO Ben Golub said the nation's largest cable operator will pay an unspecified amount for the social networking company, although Reuters reported the price tag will fall between $145 million and $175 million.

"Comcast has an exciting vision to bring the social media experience to mainstream consumers," Golub wrote. "Together, we will be able to help users connect with all the people they care about, across all of the devices they use, with all the media they love to consume, create, and share. This is also great news for the Internet industry at large, where Plaxo has been -- and will continue to be -- a strong advocate for opening up the social Web."

Golub went on to say that the acquisition is subject to the satisfaction of customary closing conditions and regulatory approvals, and is expected to close in the near future.

Comcast's stock was losing 10 cents, or 0.5%, to $22.27. Among other pay-television providers, DirecTV (DTV Quote), Cablevision (CVC Quote), Dish Network (DISH Quote) and Time Warner Cable (TWC Quote) were also slightly lower.
